Nucleotides & Nucleosides

Natural and modified nucleoside analogs (i.e. nucleobase linked to a sugar moiety but lacking the phosphate groups).

Important notes:

• • For your convenience we offer most nucleotides as 10 mM aqueous stock solutions (pH 7.5) which is ideal for most applications.

• • In general, all nucleotides on stock have a purity of >95 % by HPLC (dNTPs >99 %). For specific information (e.g. the amount of diphosphate in a particular batch of a non-hydrolyzable triphosphate analog…) please contact us

• • Most nucleotides are available as small (S) and large (L) packs, with an L pack equal to five S packs. Thus, when ordering an L pack, you may receive five individual S packs.

• • Unless stated otherwise, all our nucleotide preparations are long-term stable when stored at -20°C.

• • If you require large amounts (> 5 L packs) please contact us for special discounts.

• • Tubes contain only few microliters of precious nucleotide solution. In order to avoid losing liquid in the cap, we recommend spinning down the tube in a bench-top centrifuge before opening.

• • Nucleotide solutions/lyophilisates are not guaranteed to be sterile.

• • We recommend aliquoting nucleotide solutions in case they are not used up with one application, so repeated freeze/thaw cycles are avoided. Aliquotation should be carried out quickly and the aliquotes should be frozen again immediately. All nucleotides can be delivered pre-aliquoted according to your specifications – please contact us for a custom quotation.
